[Tkinter-discuss] the difference between mainloop and app.mainloop and root.mainloop?

[Steve Oldner]

Thanks.  I have seen this in some code snippets, but not have seen the destroy()

def main():
    root = Tk() 
    #stuff here
    root.mainloop()


if __name__ == '__main__':
    main()

How would I dare to decide this ;) ?

If we look at the relevant parts of the IDLE code we find the following,
and if they do it this way I guess that at least it can't be bad ;)


    def main():
        (...lots of code...)
        # start editor and/or shell windows:
        root = Tk(className="Idle")

        fixwordbreaks(root)
        root.withdraw()
        (...some more lots of code...)

        root.mainloop()
        root.destroy()

    if __name__ == "__main__":
        sys.modules['PyShell'] = sys.modules['__main__']
        main()

Regards

Michael
